To all whom t may concern:

Be it known that I, FRANCIS A. JoHNsoiv,

a citizen ofthe United States, residing at.

Kansas City, inthe *county of Jackson and State of lilissouri,haveinvented new and useful Improvements in Automatic Regulators forGasolene-Burners, ot which the following is aspecifi'cation.

This invention relatesto automatic regulators for gasolene burners, theobject yin view being to provide a regulator of the class' describedwhich is particularly de signed for heating or blow torches.l f

The invention is Vparticularly designed for welding steel rails, 'theframes of locomotives, and for heating. the" .tires of' locomotives inorder to` facilitate puttingthem on'l y and removing the samef-'from'thewheel.

Al further objectif of the invention is .to provide a device of theclass described which `will embody a maximum degree of safety,

and in which the pressure will automatically maintained at apredetermined point,

so thatthe4 air and gasolene will be properly proportioned andthoroughly mixed,

v1'c pa'1"atory to ignition.

f ,With the above and other objects in view, the invention consists inthe construction,-

combination and. `arrangement of parts, as will be hereinafterv morefully described, illustrated in the accompanying drawings, and pointedout in the claims hereunto appended.' I Y In the drawings: Figure 1 is aside elevation ofthe regulator embodying the present invention. F ig. 2is a longitudinal section through the same. Fig. 3 is a section on theline 3 3 of Fig.` 2. Fig. 4 is a longi- -tudinal section through thepressurek regulator. Y

The regulating device contemplated in this invention comprises a hollowbody 1, and a neck 2 forming a partof the body, and extendingsubstantially at right angles' to the main part of thebody, as shown inFigs. 1 and 2.- At onelend, the body is internally threaded, as at. 3,to enablea pipe from an air' compressor to berscre'wed into the body,

while, at the opposite end the body is int ernally threaded, as at et,to receive a gas pipe or hose 4', by means of which the gasolene vapormay be carried any suitable distance to the point of ignition.

The air is received 1n an air inlet chamberv 5, and the assage of airthrough the bodyj; is controllo by an air valve 6 operating -1n.conjunction with a valve seatjv'., the valve embodying a vstein 8 whichextends outward which .isinternally threaded, as shown, to

trally and longitudinally of the body, and leaves a surroundinggasolene" chamber 12,

blast ofafir passing through the n zzle `11, and atomized as it entersthe service pipe or hose. f

The neck Q-comprises a gasolene passage 13 which opens out at the lowerend of said neck, the latter being ta ered and threaded, asgshowii at14, to ena le the device as a whole to be screwed into a gasolenepressure tank 15.

vided at its lower end with a strainer cage tank 1 5, and held in placeby the tube 16. This tube is threaded atits upper end, as shownv at 18,in Fig. 2, while a ball check valve 19 rests lagainst the upperextremity of the tube 16, where a seat 20 is'formed :for -said ballcheck valve. This check valve `is employed to p prevent back nring intothe gasolene tank 15. Above the tube 16 yand check valve 19, thegasolene passage 13 is deflected laterally to one side, as shown in Fig.3 by the numeral Q1, and the wall 2:2 separating the space Q1 from thegasolenc chamber lf2 is provided with a conical opeuing forming ka vulveseat Q3, in conjunction with which a gasolene needle valve lloperatesfor regulating thel iiow ol gasblene into the chamber 1Q. The needlevalve 'is provided with a stem 25 etending outwardly through a stuffingbox, and provided with an operating wheel at its outer en d. The air andgasolene valves above described enable the quantity of air and gasoleneto be properly proportioned and regulated.-

3l designates a. p

l' opening in the top of the body l.

. Communicating with the. air duct 27, at a point intermediate the endsthereof, is an air pressure regulator, comprising a body or valve casing32, .the inner end of which is f threaded, as shown at 33, and screwedinto an internally threaded opening 34 nl 'the neck 2. Inits inner` end,the body 32. is recessed, as 'at 35, to receive a valve'holder orbushing 36, in which'is arranged a sliding cone-shaped valve 37 pressedtoward its seat bymeansof a coiled spring 38 surrounding the Stem 39 ofthe valve..- The body 32 is also chambered out to form 'a cavity 40`,-inwhich is laced .a valve seat 4l,

(against which the vave 37 is adapted to seat; The outer side of saidyalve seat is recessed to form an airpressure chamber which is closed by.means a diaphragm 43 held between the valve seat 'dit and an internelannular shoulder 44 in said body,

The body 3 is also bored out. as shown at.

d5, toreceive a threaded turn plug d@ having central bore d'7, in whichis received the stein e3 ci: a lunffer head 49 which isv pressed.towardthe diaphragm d3 by means of a coiled spring 5() encircling thestern .48 and interposed between head 3 the 'inner end or the turn plug47.

Rigidly connected to the outer end et the turn plug is a milledhead 52which is of suilicient internal diameter to embrace and renali/"eAaround the outerlend oi the body the said head 52, together with thebody 32, being graduated, as shown at 53 and ed., respectively, thegraduations 5e being intended to represent the airl pressure in pounds,so.. that by turning the head 52, any desired rpressure in pounds may heobtained in the air regulating chamber l2 By turn the head 52, the turnplug is `Lei/'oli' and pushes inward on the spring i I cordingly exertsa greater or less l lug inserted in a threaded v Lozsgelii against theplunger head' 49, and in turn against the dlaphragm, .tending to2 openthe port through the valve seat 4l; 0n the other hand, the spring 38Abehind the valve 37 opposes the action of the spring 50. Air entersthe. chamber 4t2 through an .air .inlet port 55 and emerges therefromthrough a port 56 which leads bach into the main air lfroin theforegoing description, it will now be seen that the air passing downwardthro'u h the duct 27 passesbyv the valve 37 and t rough the chamber 4:2and port 56 into the end portion ofthe duct 27, and thence inte thegasolene tank. Should the air pressure in the tank diminish ilo-'anyconsiderable extent, the pressurevv in the chamber 42 will becorrespondingly reduced,

thereby allowing Athe spring 50 to move the plunger head and therebyforce the diaphragm 43 against the endof the valve 37,

unseating said valve and allowing the full 'ainpressure to enter thechamber 4-2. As

soon as the pressure is restored, the valve 37 closes and shuts od'any-'further increase in pressure. In this Way, a certain predeterin'ined pressure is always maintained in the gasolene tank, whichwill insureV the proper dow-'o -ga'sclene under pressure to the needleyvalye 24:.
